refers to a persistent pain felt along the sciatic nerve, which
runs from the lower back, down through the buttock, and into the
lower leg. Sciatic pain can feel like numbness or tingling and may
run down through the knee or reach all the way through to the foot.
The sciatic nerve is the longest and widest nerve in the body,
running through the piriformis muscle (which is in the buttock). It
controls the muscles of the lower leg and provides sensation to the
thighs, legs, and the soles of the feet. When the low back is
out of alignment the muscles contract to try to protect the low
back. The contracture of the piriformis muscle can squeeze on the
sciatic nerve. The sciatic nerve can also be irritated when
there is a mis-alignment of the lumbar vertebra or sacrum which
puts pressure on nerve.
Although sciatica is a relatively common form of low-back and leg pain, the true meaning of the term is often misunderstood. Sciatica is actually a set of symptoms—not a diagnosis for what is irritating the nerve root and causing the pain.
Sciatica occurs most frequently in people between the ages of 30 and 50 years old and those with a highly active or highly sedentary lifestyle. Most often, it tends to develop as a result of general wear and tear on the structures of the lower spine, as opposed to a result of injury.
What are the symptoms of sciatica?
Most commonly, patients who suffer from sciatica experience pain that radiates along the path of the sciatic nerve, from the lower back and down one leg, typically felt on one side of the body.
Sciatic might also cause:
- Mild tingling
- Dull ache
- Burning sensation
- Pins-and-needles sensation, most often in the toes or foot
- Numbness or muscle weakness in the affected leg or foot
- A sharp pain or ache in the heel of the foot
It is important to note that pain from sciatica often begins slowly, gradually intensifying over time. In addition, the pain can worsen after prolonged sitting, sneezing, coughing, bending, or other sudden movements.
How can sciatic pain be treated?
For most people, sciatica responds very well to conservative care, including chiropractic. Keeping in mind that sciatica is a symptom and not a stand-alone medical condition, treatment plans will often vary depending on the underlying cause of the problem.
Chiropractic offers a non-invasive (non-surgical), drug-free treatment option. The goal of chiropractic care is to restore spinal movement, thereby improving function while decreasing pain and inflammation. Depending on the cause of the sciatica, a chiropractic treatment plan may cover several different treatment methods, including but not limited to spinal adjustments, ice/heat therapy, ultrasound, TENS, and rehabilitative exercises. In general, sciatica is treated by corrected the mis-alignment, performing muscle work to relax the muscle, and with flexion/distraction. Flexion/distraction is a treatment in which the vertebrae are gently separated to take pressure off of the disc and nerve.

Can sciatica be prevented?
While it’s not always possible to prevent sciatica, consider these suggestions to help protect your back and improve your spinal health:
- Maintain a healthy diet and weight
- Exercise regularly
- Maintain proper posture
- Avoid prolonged inactivity or bed rest
- If you smoke, seek help to quit
- Use good body mechanics when lifting
